Microevolution is caused when fit or adaptive allele (phenotypic traits) is passed from one generation to another through reproductive success over time. Natural selection (fitness) which is mostly dependent on how successful and organism reproduces and survive influence an organism's phenotype. These phenotypic traits is large a product of alleles, or genes an organism possesses
Fitness is used to describe the reproductive success of an organisms compare to others in the same population.These fitted organisms are able to resist the environmental pressures, and are naturally selected due certain hereditary traits which contributes to their fitness called adaptation.
Therefore<em> when these traits contributed to higher rate of reproductive success, then they are describe to be the</em> fittest, well adapted and therefore naturally selected in the population.
Usually, the oceanic plate is heavier than the continental plate. This is because the oceanic plate is ‘wet’ from the percolated oceanic water in its crust. Therefore, it is submerged by the continental plate, As they collide. the crust (especially the continental plate) folds hence casing uplifting and formation of fold mountains such as the Himalayas.
Because green house air is like carbon dioxide and is toxic for people to breathe in but they want to put it under an act that says it will cause u no harm
